Technical Field

[0001] The invention belongs to the technical field of forging cooling, and in particular relates to cooling equipment for forging automobile parts. Background Art

[0002] Most of the auto parts are produced by forging. The auto parts that need to be forged are: engine body, cylinder head, clutch housing, drive rear axle; forged: crankshaft, half shaft, camshaft, connecting rod, valve push rod. After the forging of auto parts is completed, in order not to affect the performance of the parts, coolant is needed to cool the parts.

[0003] The existing cooling equipment for forging has the following problems: Existing cooling equipment for forging processing does not have the ability to place the forging into a coolant of an appropriate depth for cooling according to its own weight, resulting in uneven cooling of the forging as a whole and increasing the risk of local deformation and cracks in the forging. In addition, traditional cooling equipment for forging processing does not have the ability to filter out impurities in the coolant after cooling, which hinders the transfer of heat from the forging to the coolant. Therefore, it cannot meet the existing use requirements of cooling equipment for forging processing. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a cooling device for forging automotive parts, which can make the forging enter the coolant to a suitable depth according to its own weight and can filter out impurities in the cooled coolant.

[0005] The technical scheme adopted in this scheme is as follows: A cooling device for forging processing of automobile parts proposed in this scheme includes a base, a cooling box, an equal-volume cooling mechanism and a liquid return type filtering mechanism. The cooling box is symmetrically arranged on the upper wall of the base, and the cooling box is arranged with an upper end opening.

The rod is fitted with the measuring end of the weighing sensor; the driving mechanism includes a driving electromagnet and a lifting magnet, the driving electromagnet is symmetrically arranged on the upper wall of the shrinking platform, the lifting magnet is symmetrically arranged on the bottom wall of the supporting platform, and the driving electromagnet and the lifting magnet are arranged opposite to each other; the cooling mechanism includes a cooling seat, a thermoelectric cooling sheet and a cooling copper plate, the cooling seat is arranged on the side wall of one end of the cooling box, the thermoelectric cooling sheet is arranged on the side of the cooling seat away from the cooling box, the cooling copper plate is penetrated through the inner wall of one end of the cooling box close to the thermoelectric cooling sheet, and the cooling end of the thermoelectric cooling sheet penetrates the cooling seat and fits with the cooling copper plate.

[0007] When in use, in the initial state, the spring is in an extended setting, and the automobile shaft forgings to be cooled are placed on the upper wall of the weighing seat inside the arc seat. The automobile shaft forgings apply pressure to the weighing seat, and the weighing seat drives the weighing rod to slide along the inner wall of the bearing platform to squeeze the weighing end of the weighing sensor. The weighing sensor detects the weight of the automobile shaft forgings, and then drives the electromagnet to be energized to generate magnetism. The driving electromagnet and the lifting magnet are set with opposite poles. The driving electromagnet is fixed on the upper wall of the shrinking platform and absorbs the lifting magnet by magnetic force. The lifting magnet uses the deformation of the spring to drive the bearing platform to descend. The bearing platform drives the automobile shaft forgings through the arc seat and the weighing seat to immerse in the coolant inside the cooling box. The thermoelectric cooling sheet cools the cooling copper plate through the cooling end, and the cooling copper plate cools the coolant inside the cooling box, thereby cooling the automobile shaft forgings.

[0008] Preferably, the liquid pressing mechanism comprises a liquid pressing copper plate and a one-way liquid pressing valve, the liquid pressing copper plate is arranged on the outer side of one end of the supporting platform close to the spring, the end of the liquid pressing copper plate away from the supporting platform is slidably arranged on the inner wall of the cooling box, and multiple groups of the one-way liquid pressing valves are penetrated and arranged on the inner wall of the liquid pressing copper plate; the filtrate mechanism comprises a filtrate trough, a filtrate box and a filter screen, the filtrate trough is arranged on the upper wall of one end of the cooling box, the filtrate trough is opened on three sides, the filtrate box is arranged between the cooling boxes, the filtrate box is opened at the upper end, and the filter screen is arranged on the inner wall of the bottom of the filtrate box; the liquid return mechanism comprises a one-way liquid return valve and a liquid return pipe, the one-way liquid return valve is connected and arranged on the side of the cooling box away from the thermoelectric cooling sheet, and the liquid return pipe is connected and arranged between the bottom wall of the filtrate box and the one-way liquid return valve; the impurity removal mechanism comprises a impurity removal plate and an impurity blowing pump, the impurity removal plate is arranged on the upper wall of one end of the cooling box away from the filtrate trough, and multiple groups of the impurity blowing pumps are arranged on the side of the impurity removal plate close to the cooling box.

[0009] During use, when cooling the automobile shaft forgings placed inside the arc seat, the bearing platform drives the liquid pressure copper plate to descend, and the liquid pressure copper plate slides along the inner wall of the cooling box into the cooling box to squeeze the coolant, and the squeezed coolant enters the upper wall of the liquid pressure copper plate through the one-way liquid pressure valve, so that the automobile shaft forgings are submerged in the coolant. When the automobile shaft forgings immersed in the coolant inside the cooling box cool down, the driving electromagnet is powered off and demagnetized, and the spring elastic reset drives the bearing platform to rise to the original position, and the bearing platform drives the bottom wall of the liquid pressure copper plate to be set horizontally with the bottom wall of the filtrate tank. Due to the existence of , one end of the cooling box close to the filtrate box is lower than the height of the other three sides. In the process of the liquid pressure copper plate rising, the coolant containing impurities dropped from the automobile shaft forgings stored on the upper wall of the liquid pressure copper plate passes through the filtrate tank and enters the filtrate box. The coolant is stored in the filtrate box in advance. When the liquid pressure copper plate rises, the liquid pressure copper plate draws the coolant in the filtrate box through the return pipe for replenishment, and the cooled automobile shaft forgings are taken out from the arc seat. The impurities remaining on the wall of the liquid pressure copper plate are removed by the impurity blowing pump through the jet end to the wall of the filter net, thereby completing the cooling operation of the automobile shaft forgings.

[0010] Specifically, a controller is provided on the side wall of the filtrate box.

[0011] Wherein, the controller is electrically connected to the weighing sensor, the driving electromagnet, the thermoelectric cooling sheet, the cooling copper plate and the impurity blowing pump respectively.

[0012] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, this solution adopts a combination of a gravity detection sinking structure and an automatic liquid replenishing structure. Through the provision of an equal volume cooling mechanism and a liquid return filtering mechanism, the shrinking mechanism, the weighing mechanism, the driving mechanism, the cooling mechanism, the liquid pressing mechanism, the liquid filtering mechanism, the liquid return mechanism and the impurity removal mechanism can be used in coordination with each other to immerse the automobile shaft forgings to a depth appropriate to the weight value of the forgings themselves. Since the weight of the forgings is proportional to the amount of heat absorbed, the greater the weight, the more heat absorbed. Therefore, in the measurement structure of the weighing sensor, Under the condition that the automobile shaft forgings are immersed in the coolant of corresponding depth, it can ensure the rapid cooling of the forging surface, and at the same time avoid the excessive cooling of the inside of the automobile shaft forgings due to the coolant being too deep, thereby generating excessive thermal stress, thereby improving the cooling effect of the automobile shaft forgings. The bearing table drives the automobile shaft forgings to be immersed in the coolant inside the cooling box through the arc seat and the weighing seat. The thermoelectric cooling sheet cools the cooling copper plate through the cooling end, and the cooling copper plate cools the coolant inside the cooling box, thereby cooling the automobile shaft forgings.

[0021] A controller 35 is disposed on the side wall of the filtrate box 26 .

[0022] The controller 35 is electrically connected to the weighing sensor 13 , the driving electromagnet 15 , the thermoelectric cooling sheet 19 , the cooling copper plate 29 and the impurity blowing pump 34 , respectively.

[0023] When in use, in the initial state, the spring 8 is extended, the bottom wall of the liquid pressure copper plate 22 and the bottom wall of the filtrate tank 25 are arranged horizontally, the coolant for replenishment is stored in the filtrate box 26 in advance, and the current passed into the driving electromagnet 15 is set to three gears: low, medium and high. When the controller 35 controls the current passed into the driving electromagnet 15 to be low, the bearing platform 7 drives the automobile shaft forging to be immersed in the upper part of the cooling box 2. The larger the current passed into the driving electromagnet 15 by the controller 35, the stronger the magnetic field strength between the driving electromagnet 15 and the lifting magnet 16. When the controller 35 controls the current passed into the driving electromagnet 15 to be medium, the bearing platform 7 drives the automobile shaft forgings to be immersed in the middle of the cooling box 2. When the controller 35 controls the current passed into the driving electromagnet 15 to be high, the bearing platform 7 drives the automobile shaft forgings to be immersed in the bottom of the cooling box 2.

The bearing platform 7 drives the liquid pressure copper plate 22 to descend. The liquid pressure copper plate 22 slides along the inner wall of the cooling box 2 and enters the cooling box 2 to squeeze the coolant. The squeezed coolant enters the upper wall of the liquid pressure copper plate 22 through the one-way liquid pressure valve 23, so that the automobile shaft forgings are immersed in the coolant at the bottom of the cooling box 2. The heavy forgings have a wide heat dissipation area and require more sufficient cooling to ensure that the overall temperature drops evenly.

In the process of the pressure liquid copper plate 22 rising, the coolant containing impurities dropped from the automobile shaft forgings stored on the upper wall of the pressure liquid copper plate 22 passes through the filtrate tank 25 and enters the filtrate box 26; When the liquid pressure copper plate 22 rises, the liquid pressure copper plate 22 draws coolant from the filtrate box 26 through the liquid return pipe 31 for replenishment under the unidirectional conduction effect of the one-way liquid return valve 30, and then the cooled automobile shaft forgings are taken out from the arc seat 9. The controller 35 controls the impurity blowing pump 34 to start. The impurities remaining on the upper wall of the liquid pressure copper plate 22 are removed to the upper wall of the filter screen 27 through the jet end. The coolant filtered by the filter screen 27 falls to the bottom of the filtrate box 26 for storage, thereby completing the cooling operation of the automobile shaft forgings; the above operation can be repeated when used next time.
